"with both devices you have a very good performance. The sound quality of both devices is nearly the same! If you don’t need a streaming client unit for internet radio or/and playing audio files from a USB HDD or NAS server and if a very heavy and high quality CD-tray mechanism is important for you, then I want to recommend PDP3000HV. If the streaming client function is more important for you than a very heavy tray mechanism, then I want to recommend MP3100HV. Of course MP3100HV supports a high quality tray mechanism too, but a bit more light construction than PDP3000HV.
I hope, these informations are helpful. If you have some more questions, don’t hesitate to contact me again."
